• AL3157FSG-EVM Rev.1, Evaluation Module for the AL3157 is a low noise, constant frequency charge pump DC/DC converter that uses a dual mode load switch (1x) and doubling (2x) conversion for white LED applications. The AL3157 is capable of driving three channels at 30mA for small-screen backlight and an additional channel of up to 210mA for LED flash, all from a 2.7V to 5.5V input. The current sinks may be controlled using two PWM dimming inputs, one for the 30mA channels and one for the 210mA channel
